So, I’ve been working on a simple physics system, and have gotten
to the point where passing around a tuple just isn’t cutting it.
Can anybody suggest a good 2D vector implementation?
This thread came up sometime last year, and several implementations
were put forward.
If you're happy to put all of your vectors into a single numpy/
numeric array, that is the fastest approach.
CGKit (http://cgkit.sourceforge.net/) is a C extension which is the
fastest vector-is-an-object implementation. Unless things have
changed recently though, this library is a nightmare to compile and
install.
For pure Python, the fastest implementation is my euclid module:

were posted in the previous thread).
Cheers
Alex.
